DISTRIBUTION in
North Carolina: Nearly statewide; more numerous in the
mountains than in the other provinces. Possibly absent in a few
counties near the coast. No records from north of Albemarle Sound
or from the eastern "Pamlimarle" Peninsula, and just one record for
the Outer Banks.

ABUNDANCE in
North Carolina: Fairly common to locally very common in the
mountains; mainly uncommon in the Piedmont and upper Coastal Plain;
rare in most of the Coastal Plain.

FLIGHT PERIOD in
North Carolina: Late March to late October. Probably three
broods, but some references suggest that there are just two broods
in our area. Downstate generally from late March to late May, early
June to late August, and a small brood in September and October. In
the mountains, mid-April to mid-June, late June to late August, and
in September and October. As with nearly all swallowtails, the gaps
between flight periods are small and almost overlapping.
